How To Find And Delete Duplicates In Google Sheets

Google Sheets is a powerful tool for organizing and analyzing data. However, when working with large datasets, it is common to end up with duplicate entries. These duplicates can cause inaccuracies in your data analysis and take up unnecessary space. In this article, we will show you how to find and delete duplicates in Google Sheets using various methods.

Finding Duplicates Using Conditional Formatting

One way to find duplicates in Google Sheets is by using conditional formatting. This method highlights any duplicate values in a column, making it easy to identify and delete them.

1. Select the column that you want to check for duplicates.
2. Click on the Format menu and select Conditional formatting.
3. Under the Format cells if… dropdown, select Custom formula is.
4. Enter the following formula: =countif($A$2:$A,$A2)>1
5. Select the formatting style you want to apply to the duplicate values.
6. Click on Done.

This formula will highlight any duplicate values in the selected column. You can then manually delete the duplicate rows or use the Filter tool to select and delete them in bulk.

Finding Duplicates Using the Remove duplicates Tool

Google Sheets also has a built-in Remove duplicates tool that can quickly remove duplicate rows from your sheet.

1. Select the range of cells that you want to check for duplicates.
2. Click on the Data menu and select Remove duplicates.
3. In the Remove duplicates dialog box, select the columns that you want to check for duplicates.
4. Click on Remove duplicates.

This will remove all duplicate rows from the selected range, leaving only the unique values. Note that this method permanently removes the duplicate rows, so make sure to back up your data before using it.

Finding Duplicates Using a Custom Script

If you need more advanced functionality for finding and removing duplicates, you can use a custom script in Google Sheets. Here is an example script that removes duplicate rows based on a specified range:

function removeDuplicates() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
var data = sheet.getDataRange().getValues();
var newData = [];
for (var i in data) {
var row = data[i];
var duplicate = false;
for (var j in newData) {
if (row.join() == newData[j].join()) {
duplicate = true;
}
}
if (!duplicate) {
newData.push(row);
}
}
sheet.clearContents();
sheet.getRange(1, 1, newData.length, newData[0].length).setValues(newData);
}

To use this script, open your Google Sheet, click on Tools and select Script editor. Paste the script into the editor and save it. Then, run the script by clicking on the Run button. This will remove all duplicate rows from the active sheet based on the entire range of data. (See Also: How To Get Day From Date In Google Sheets)
